To all whom-it concern." .Y

Be it' known that I, Orrmme. 0. CALEFF, e

citizen of the United States, and a resident' of Boston, in the county of Suffolkigtnd Commonwealth of Messachuse'tts,i hevei'kilb vented certain new lend nseful'lm rovexnents in Gasfumrs, Oflwhch the fpl owingiela funs' 1310er.- nfl exact speceat10n- Theobject of this invention is the effect- .ingesting movements in that type of ,gas .burners'lfw ich is adapted to be located within a cooking range, the special features of the improvements relating to means for increasing the heat directed against both the waiter-front and the oven-wall, and also to` better'sitpply the heat to the range-top.

is providedv for shutting oil' the su In. the drawings forming part of this specification, Figure 1 is e perspective view of aggs burner embodying my improvementsi Fig. 2 is a. cross section thereoi` showing its designed -location in a. range.

Fig. 3 is a sectional detail View of one of the valves. .1

The burning ges is supplied to the burner through a pipe lfsuitehly su pliedwith air, es through an eirsupp`ly evice 2. This ipe" 1 is tapped into e. central boss 3 gf en lzlhaped member 4, from' which rises n pipe-section 5. Into the' branches-6 o the H-member are tapped two burner tubes providedwith burner openings 9.-V I,

At the upper end of the verti4 al section 5 is a. T 10, from which' s feeder sectio'n'll` extends parallel with the` burner tubes 7 this section 11 having two X-couplinv s lsnd 13 from the lateral branches 14 o which project short burner tubes 15., Both thetubes 15 and the X-couplings are provided'with burner openings 17. .f 1;'

From the branch of the Tfzlghpposite the feeder section 11, projectsa vlve-stem and actuating handle 1 9 constructedfor closing the entrance tothe section 'il and thereby shutting off wholly onfpnrtiallvthe su ply of gas-thereto, as showninFig. 3 Vimilerly a valve 18' and actueting hand-pielce- 1i;

P Y 0 gas to each of theburner tubes',v oth 'or either, wholly or partially.

Beneath the burner tubes T'and above thc supply pipe 1 is'loceted a. baille platel 2O suitably curved us showninFig. 2te 'lit the same;l this plate extending "practically the entire length of the burner-tubes.

As shown in Fig. 2, the ges burner is rested directly1 upon the grete'21 of the 'fire 'cups 25 so as pot 22 of a rengglfvrliil burner tubes.` 15 cometles 23 ci the stove. Thecrcs'sgmse l? agie -gesigiied to f e' t e ront stnvlgfv i" trate their hee'iug or whenV the letter" bottom of the peto .Thus placed,.`a.ll th. by the cross-wise-burne purposes; or thevelvevif .$58861 1 be closed nndbothlbui'netubes'-perm to do the heating for warming both .the Water-front of the range4 and t e oven; or 10 the Water-trout can be given lell the heet.; or the oven can be heated alone, or all the burners can be simultaneously supplied v'vith gas and give the maximum of heut. i

The purpose of the baffle plefte 20 is to 75 shut oii' l the admission of too much eil' through the grate. and also to concentrate a. l supply of heated air to the burner tubes 7.V y The central portion of the plate being'over the supply pipe 1, `is brouoht nearer Ithe 80 burner flame and is strongly heated thereby. Moreover, the concave under surface of the plate 20 provides n pocket for holding there- Ying gas issuingfrom the burner holes with e maximum temperature` further aiding in the combustion sind et the seme time incepable of cooling the' open or the water front es it rises. e

Another purpose in thus arranging the'95 bniiie plete is to fasten it in place so that theburner een be shipped without danger of its y being forgotten or misplaced. Although' for the sake of clearness of 'llustretiom have shown the baille plate 20 as Hush with' 100 the faces-of the4 ytubea s 25, I prefer to press it Vferther in to ring its terminal edge 26 just Within theinnirfedges of the to lock itffin place thereby;

1illr'hettl claim is: .A Vp 105 1. A ges burner for stoves and rmige's, com rising -burner tubes designed to be lo cete at the bottom of vertical pipe section risingtherefronip df'izontel feeder section connected tvith e upper end of said vertical section. tryo crosseections. communicating with and supported by Stm' curved to horizontal section to come immediately beneath the two stove covers, and means for supplying said tubes and seetions'with burning gas, said crosssect1ons having burner openings along,r their upper surfaces.

of 4said vertical section, a, horizontal feeder setion supported by said T and having two X-couplings therein, cross burner tubes projecting laterally from said'X-oouplings, a

valve for said feeder section, and a valve for each of the first-named burner tubes.

3. A Ygas burner for stoves and ranges comprising two parallel burner tubes, and a gas supply pipe disposed midway of and parallel with said burner tubes and connected with the lattenand a baffle plate pass above the supply pipe and to have its lateral edges'come beneath said burnertubes.

vparallel with said tubes, and a baille 4. A gas burner for stoves and ranges comprising a pair of parallel burner tubes, meansjor supplying them with burning gas, and a balie plate having its lateral edges l0- cated beneath said tubes.

5. A gas burner for stoves and ranges vcomprising a pair of parallel burner tubes, means for supplying them with burning gas, and a balile plate heving-its under surface concave and its lateral edges locatedbeneath said burner tubes. y

6. A lgas burner forstoves and ranges comprising two burner tubes each closed at one end, thev closing means consisting of a cap screwed thereon, means. for supplying burning gas to the other ends ef said tubes consisting of a pipe lying midway of ind ate curved to have its lateral edges locate beL neath said tubes and its intermediate portion to cover said supply pipe.

In testimony that I claim the foregoing invention I have hereunto set my hand this 3rd day of November, 1920.
